General Description

The LMK5B33414 is a high-performance network synchronizer and jitter cleaner designed to meet the stringent requirements of ethernet-based networking applications with < 5-ns timing accuracy (class D).

The network synchronizer integrates three DPLLs to provide hitless switching and jitter attenuation with programmable loop bandwidth and no external loop filters, m
